I've never had an issue with drying time or mildew with my RC midweight pieces. I've even thrown a shirt into a tumble dry and didn't notice any shrinking. This brand is really easy to care for and lasts a long time. Also just putting it out there - our prices are in CAD (approx 77 cents USD), and we have free shipping to USA for orders over $150
This has been our experience too - Reigning Champ midweight / core program stuff is ultra shrink resistant. i've machine washed / dried 2-3 pieces multiple times each and they really haven't changed their shape.
they really are the best sweatshirts for the money if you want high value. Geller will be more luxurious and softer for 3x the price, but RC is easily the best in it's price bracket.
